Us Weekly is reporting that Drew Barrymore has ended her four year relationship with rocker boyfriend Fabrizio Moretti, drummer for the The Strokes. 'Drew said they needed time off,' an insider told Us Weekly magazine.And a pal of Moretti's says the musician has now moved back into his own apartment. The couple's relationship has not always been smooth sailing. In February 2005 Barrymore, 31, skipped the wedding of Strokes frontman Julian Casablancas. And several months later they were spotted having a public row in Santa Monica, California. 'He's younger and she's more worldly,' another insider told the magazine. 'He doesn't like the Hollywood stuff. He doesn't get her friends.' This guy is a rock star, why was he wasting his time dating Drew Barrymore when he could have been (and should have been) spending lots of quality time backstage with groupies, sleeping with models, and deflowering fans. What a waste of fame. Pictures by Ginsburg/Spaly
